Gypsum Block Production Machine bearing temperature is abnormal
For bearings that play an important role in the work of Gypsum Block Production Machines, only the timely resolution of their faults can keep the equipment working smoothly, and different solutions have different solutions. Here we are here. Introduce the phenomenon of abnormal temperature that occurs when the bearing is working, what is going on.
For the bearing of the Gypsum Block Production Machine, it runs under the complicated environment of high temperature, impact, heavy load and low speed. Therefore, if it is not properly maintained, it will cause its failure and the phenomenon of abnormal temperature. It is easy to cause the electric breaker of the Gypsum Block Production Machine to be cut off frequently, which seriously affects the production progress. Generally speaking, the main causes of this phenomenon are: insufficient lubrication, the internal bearing of the grinding roller enters a large amount of powder, the sealing system is damaged, and the grinding roller bearing Local damage and excessive internal grease and impurities, here's a look at these aspects:
1. Insufficient lubrication
The reason for the lack of lubrication of the Gypsum Block Production Machine may be due to the incorrect selection of the type of lubricating oil. Generally speaking, the working temperature of the grinding roller bearing is relatively high, and the temperature inside the bearing is close to 200 ° C. If the type of lubricating oil is wrong. Then, the oil used for lubrication will be deteriorated or evaporated due to high temperature and high pressure, thereby losing the function of protecting and lubricating the grinding roller bearing, which will increase the heat generated by the friction of the grinding roller bearing, thereby causing abnormal bearing temperature. Raise, in addition, if the Gypsum Block Production Machine has too little oil, or the replacement is not timely, it may cause the lubricating oil to lose its original effect, resulting in insufficient lubrication of the grinding roller bearing, which will also cause the bearing temperature to rise. Premature damage to the bearing occurs.
The treatment of this phenomenon is to choose the viscosity and the synthetic grease which is stable at high temperature when selecting the lubricating oil, so as to ensure the lubrication of the Gypsum Block Production Machine bearing is guaranteed, and the bearing runs every time. For four months, it must be replaced in time, and each time you pay attention, you should pay attention to the oil should not be less than forty liters.
Second, the internal bearing of the grinding roller enters a large amount of powder
If the internal bearing of the Gypsum Block Production Machine enters a large amount of powder, then these powders will bond with the lubricating oil and become a viscous and extremely poorly mixed powder-oil mixture, which will not Any lubrication will also increase the wear of the bearing, causing the temperature of the roller bearing to rise abnormally.
The solution to this phenomenon is to immediately replace the oil seal when the powder enters the bearing and cause the bearing temperature to rise abnormally, and check the quality of the lubricant to ensure that it does not deteriorate. If there is too much powder accumulated in the bearing of the crusher, and the powdered oil mixture cannot be discharged with the oil outlet, the inner end cover of the bearing can be opened, and the mixture of the powder and oil can be discharged by compressing air or adding hydrogen. Add new lubricant.
Three, the sealing system is damaged
For the Gypsum Block Production Machine, the sealing air system is the key to ensure that the oil seal of the grinding roller is not damaged. It is mainly composed of a sealing fan and a duct. The blown air starts from the sealing fan and reaches the sealed air duct. The mounted grinding roller seals the air to form a space, so that an annular sealing and cleaning system can be formed, which can ensure that the powder does not enter the grinding roller bearing, and can prevent the powder from damaging the oil seal, and the various links are closely connected, and are indispensable. If there is a problem in any link, if there is air leakage or debris, the pressure of the air seal ring will decrease and the air volume will be insufficient. This will cause the annular air seal system to be unable to form, which will result in mobile A series of conditions in which the oil seal of the crusher is damaged, the powder enters, and the bearing temperature rises.
The solution to this phenomenon is to stop the production immediately and investigate when the temperature of the roller rises abnormally. From the sealing fan, check the direction of the wind step by step, so as to block the loophole and seal the solution in time. seal. Due to the harsh working environment of the Gypsum Block Production Machine and the long-term and large amount of powder, the fan filter is easily blocked. In this case, the technicians should clean up and try to do it once a month, and because of the working environment. The temperature is higher, the air duct is easy to soften or deform, or there is a phenomenon of air leakage. It should also be checked for half a month on the Gypsum Block Production Machine to kill the fault in the cradle.
